SPECIFICATION forming part of Letters llatent No. 665,589, dated Jame s, 1901.

Application filed August 13, 1900. Serial No. 26,765. (No model.)

To all whom it may concern:

Be it known that I, LOUIS D. VOGEL, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nobraska, have invented a new and useful Machine for Making Barrel-Heads, of which the following is a specification.

My invention is an improved machine for making circular covers and bottoms, the object of my invention being to provide an improved machine which is adapted for sawing out circular articles-as heads, covers, and bottoms for barrels, vats, tanks, tubs, and the like-of any required size and for beveling and finishing the edges thereof while the same are being sawed.

My invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of a machine embodying my improvements. Fig. 2 is a vertical longitudinal central sectional view of the same. Fig. 3 is a detail sectional view of the revolving table, taken on the line a a, of Fig. 1. is an end elevation of my improved machine. Fig. 5 is a transverse vertical sectional view of the same, taken on the line b b of Fig. 1.

The bed 1 of the machine comprises a pair of parallel rails 2 and supporting-blocks 3 4, which are respectively disposed at the outer ends and near the inner ends of said rails. Vertical standards 5 6 rise from the inner ends of the rails 2,and formed with said standards, at the upper ends thereof, are curved arms 7 8, which extend inwardly over the bed a suitable distance and are united together, as shown.

A pivot-block 9 is supported and guided between the rails 2 and is adjustable thereon and provided with a clamping-bar 10 and bolts 11, by means of which said pivot-block may be secured to the rails at any required adjustment. A circular revoluble table 12 is provided with a central axle-stud 13, which turns in the block 9, and thereby the said table is adapted to revolve on said block. A block 14 is secured between and adjustable on the rails 2 and is provided with aclampingbar 15 and bolts 16, whereby it may be socured at any required adjustment, and the Fig. 4

which rises from the center of the supporting block 4, and in a block 20, which is secured between the rails 2 of the bed. A spur-gear 21 is fast with said feed-roller 18. It will be observed by reference to Fig. 2 of the drawings that the rollers 17 18 support the table 2 in a horizontal position. The table is removable from the block 9, and in practice a number of the tables are provided for each machine, the said tables being of various sizes corresponding with the sizes of the heads, covers, or bottoms to be made.

A shaft 22 has its inner end journaled in a bearing formed in the block 20 and its outer end journaled in a suitable bearing with which the bed is provided. A pinion 23 on said shaft engages the gear 21, and said shaft is provided at its outer end with a gear-wheel 24 and a sprocket-wheel 25.

A shaft 26 is journaled in a bearing 27 under the block 4 and in a suitable bearing 28. Said shaft has a pulley 29 and is further provided with pulleys 3O 31. A reversing-lever 32 is fulcrumed on the standard 5 and carries a pair of pinions 33 34, which are engaged with each other and are adapted to be alternately engaged with the gear-wheel 24 on the feed-shaft 23, the fulcrum of the reversinglever 32 being eccentrically disposed with reference to the feed-shaft 22. .A pulley-35 is fast with the pinion 34, and said pulley is connected to the pulley 31 on the shaft 26 by an endless belt 36. A suitable belt-tightener 37, which carries a sheave 37 that engages said belt, keeps the same at all times at the requisite tension.

In the sawing of circular work of the kind for which my improved machine is adapted it is desirable and necessary to sometimes reverse the rotation of the table to enable the saw to work in either direction, as may be required by the direction of the grain of the wood, or to back the saw in the kerf to clear the same of sawdust, and for other reasons such as will be understood by those practically engaged in the operation of machines of this class and it will be understood from the foregoing that by reversing the lever 32 the direction of rotation of the table 12 may be reversed, the respective pinions 33 34 being adapted to rotate the feedshaft 22 in either direction by engaging the gear-wheel 24.

A block 38 is vertically adjustable in a head 39, with which the arms 7 8 are provided at their meeting ends. A screw-rod 40 extends upward from the said block 38, passes through the upper side of the head 39, and is provided with an adjusting-nut 41, which serves to limit the descent of the block. A weighted lever 42 bears on the said screwrod and serves to normally depress the block 38. A block 43 is vertically adjustable in a yoke 44, which connects the standards 5 6. An adj nsting-screw 45 and nut 46 are provided for vertically adjusting the block 43, and in said block 43 and in block 38 is journaled an upper feed-shaft 47, which carries an upper feed-roller 48, that bears on the upper side of the work on the table 12. For the purposes-of illustration the work is indicated by dotted lines at A in Fig. 2 of the drawings. The upper feed-shaft 47 is provided at its outer end with a sprocket-wheel 49. Said sprocketwheel 49 is connected to the sprocket-wheel 25 on the lower feed-shaft 22 by an endless sprocket-chain 50. Hence power is communicated from the lower feed-shaft to the upper feed-shaft and both are rotated in unison, the lower feed-roller 18 bearing under the table 12 and the upper feed-roller 48 bearing downward on the work on the said table, said feed-rollers coacting to revolve the table and the work thereon. The weight 42 on the lever 42 is adjustable thereon, so that the compression of the upper feed-roller on the work may be varied as may be required. A belttightener 51 is provided for the endless chain 50. The said tightener comprises a lever 52, which is fulcrumed on the standard 6, a hearing sheave or roller 53 at the inner end of said lever and which bears against one lead of the chain 50, and a Weight 54, which is adjustable on the outer arm of said lever.

A U-shaped guiding-yoke 55 is on theinner side of one of the rails 2 near the standard 6. A head 56 is vertically adjustable on the ways formed by the sides of the yoke 55 and is provided on its rear side with a lug 57, having a threaded opening which is engaged by an elevating screw-shaft 58, the lower portion of which hasits hearings in the lower side of the yoke. A crank-shaft 59 is journaled in suitable bearings 60 and extends from the front side of the machine to within a short distance of the lower end of the screw-shaft 58 and is geared to the latter by bevel-gears 61. It will be understood from the foregoing and by reference to the drawings, more particularly to Fig. 1 thereof,that by turning the crank'shaft the head 56 may be raised and lowered at will. A bed-plate 62 is pivoted near its inner upper corner on the head 56, as at Thereby the said bed-plate is adapted to be inclined at any required angle on the vertically-adjustable head, and the said bed-plate is secured at any required adjustment by a bolt 64, which operates in a curved slot 65, which is concentric with the pivot 63. The said bed-plate is provided at its ends with bearings 66, in which is journaled a saw-arbor 67, which carries at its inner end a concaved circular saw 68, which saws the edges of the heads, covers, or bottoms. At the outer end of the saw-arbor is a pulley 69.

A counter-shaft is disposed opposite the shaft 26 and is provided with pulleys- 71 72 73 and a loose pulley 74. An endless belt 75 connects the pulley 71 with the pulley 69 on the saw-arbor. An endless belt 76 connects the pulley 72 with the pulley 30 on shaft 26. Said shaft 70 is driven by a power-belt 77 and the pulley 73. A belt-tightener 78 keeps the belt 75 at the requisite tension at all times;

On the front side of the machine are vertically-adjustable frames 79 80, which carry the shafts 81 82 for the upper and lower beveling cutter-heads, respectively, which are employed for beveling and finishing the edges of the work. The frame 79 is adjustable by means ofa screw 83, and the frame 80 is adjustable by a screw 84, having a crank 85. The shaft 81 has a pulley 86, and the shaft 82 has a pulley 87. An endless belt 88 engages the pulley 29 and pulley 86, passes on the reverse side of the pulley 87, and connects said pulleys 29 86 87. The outer lead of said belt .88 is engaged by a stationary sheave or'roller 89, mounted on the front side of the machine, and the said lead of the said belt is also engaged by a roller or sheave 90, which is carried by a vertically-movable block 91, which travels on a vertical guide 23. Said block 91 has a vertical rack: 93-, which is engaged by a pinion 94 on a shaft 95. The said shaft has its bearings at 96. and is provided with the drum 97, on which is a cord 98, the depending end of which has a weight 99. It will be understood from the foregoing that the vertically-movable block 91 automatically adjusts itself to maintain the belt 88 at the required tension when either or both of the shafts 81 82 is raised or lowered. It will be further understood that power is communicated from the shaft 26 to said shafts 81 82, which carry the beveling-heads that operate on the upper and lower sides of the work immediately in rear of the saw.

The revolubl'e work-table 12 may be of any suitable construction. As here shown, it comprises the circular felly or rim and the crossed bars 101 102 103, which connect the felly or rim with the central blocks 104. The felly is provided on its upperside with spurs or points 105, which serve to engage the work and secure the same on the table. A pair of shafts 106 are journaled in bearings in the bars 101 and are disposed on opposite sides of the axle of the table. Said shafts are provided with operating levers 107 and with cams 108.

A pair of clamping-bars 109 are disposed on the inner side of the bars 101, bear upon the cams 108, and are adapted to be raised and lowered by said cams when the shafts 106 are partly rotated by means of the levers 107. The ends of the said clamping-bars are disposed just within the felly or rim of the table 12, which locks the same against endwise movement. Each of the clamping-bars is provided at one end, on one side,with a pivoted dog 110, the spur or point 111 of which is adapted to be driveninto the under side of the work. Near the opposite end of each clam ping-bar, on the inner side thereof, is a dog 112, which is pivoted on a stud or bolt 113, that operates in a slot 114, with which the dog is provided. Hence the dog 112 is adapted to be moved toward and from the center of the table by an adjusting and clamping screw 115. In placing the work on the table the clamping-bars are first raised above the surface of the table,

the work is placed on said clamping-bars, the dogs driven upward, so as to embed their points or spurs in the under side of the work, and the dogs 112 are moved inward by the -screws 115 to clamp the work firmly between said movable dogs 112 and the relatively stationary dogs 110. The clamping bars are then lowered, so as to cause the work to rest on the cross-bars and rim of the table and the spurs of studs of the latter to also become embedded in the lower side of the work. A weighted centering-frame 116 is then lowered on the center of the work, as indicated in dotted lines in Fig. 2. The work-table 12 is balanced on opposite sides on the front and rear sides of the machine by rollers 117, which are carried by suitable standards 118. The upper and lower feed-rollers by engaging, respectively, the upper side of the work and the lower side of the table, as hereinbefore described, rotate the table and the Work, the saw serving to cut the work in circular form of the required size and the beveling-heads carried by the shafts 81 82 operating on the upper and lower sides of the edge of the work immediately in rear of the saw and serving to bevel and finish the same, as will be understood.
